Short answer: the KRK Classic 5. It ranks #30 of 64 powered bookshelf speakers by sound quality at $280; the Kanto YU ranks #51 and costs $349.99, so there is not much of a tradeoff to weigh.
What the KRK Classic 5 offers: High-quality Klippel NFS data produces a 5.22 Spinorama preference score with a subwoofer, essentially level with the Edifier MR4. Bass reaches 60.1Hz at -3dB and 54.2Hz at -6dB, and the speaker responds especially well to EQ: Spinorama’s corrected score rises from 2.71 to 5.34 without a subwoofer and from 5.22 to 7.71 with one. Watch for: The unequalized response has a large 6.5dB frequency-deviation band, elevated splashy treble above 4kHz, crossover directivity error, and sharply narrowing tweeter dispersion. Distortion becomes extreme below 50Hz. Its raw 2.71 preference score is weak without a subwoofer, so EQ and careful toe-in are strongly recommended.
What the Kanto YU offers: A compact powered pair with RCA, aptX Bluetooth, subwoofer output, remote control and tone adjustment. ASR predicts a 5.51 preference score with a subwoofer and measured 68Hz in-room extension from the small 4-inch cabinet. Watch for: Its 2.59 standalone preference score confirms that the limited bass strongly benefits from a subwoofer. Connectivity is sparse versus newer powered rivals—no USB, optical or HDMI—and Bluetooth is the older 4.2 generation.
Buy the KRK Classic 5. It ranks higher for sound quality than the Kanto YU and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Kanto YU. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
